"""PLAN 188-1 — 종단(B05) ↔ 횡단(B06) 오갈 때 마지막 고름 하나만 이김.

원인: 종단 측점선 · 3D 띠 · 표에서 고른 일반 측점은 고름 한 칸(`structure-pick`)에 안 적혀
(`syncIrregularSelection` 이 일반 측점이면 바로 끝남) 옛 배관 고름이 남아 횡단이 배관 카드로 감.
횡단 → 종단은 관 · 구조물이 없는 자리면 그래프 측점선을 풀어 버림(`selectGraphAt` = null).
실제 TS 를 `helper_188_1_last_pick.cjs` 가 Node 로 돌린다.
